i want understand that, why composer.phar file needs updated after 60 days? why composer.phar needs updated after 60 days? composer doesn't need updated after 60 days. update recommended after time! why 60 days? i can't speak core developers on decision, can give educated guess: composer used shorter frequency recommending updates during development , alpha stages. former message warning: development build of composer on 30 days old. recommended update... . users recommended pull updates in short frequency stay on latest, bleeding-edge version. short update frequency allows users report bugs , issues project. results in fast feedback , development cycle fast roll-outs of new versions address urgent issues. now, composer released stable time increased 60 days, because (i guess) fast feedback cycle no longer needed. reflects project no longer in pre-release/alpha development mode, has stabilized. stats might lie, might take @ issue tracker find m...

i wrote script makes use of selenium, installed selenium through pip. there way can distribute script others without having them install selenium through pip? i looking at: https://pypi.python.org/pypi/selenium#downloads would if included source distribution of selenium pypi in project folder? people have click on source distribution's install.py install selenium? you can use setuptools , use install_requires keyword. like this: from setuptools import setup setup( # options install_requires = ['selenium'], ) see tutorial here then when install package/module using pip, selenium installed.

in php can start transactions when performing queries. when should use it? bad use feature every query? or should use query when adding/removing/updating large quantities of data? example of transaction: try { $db->begintransaction(); $db->exec("some query"); $stmt = $db->prepare("another query"); $stmt->execute(array($value)); $stmt = $db->prepare("another query again??"); $stmt->execute(array($value2, $value3)); $db->commit(); } catch(pdoexception $ex) { //something went wrong rollback! $db->rollback(); echo $ex->getmessage(); } my guess would heavily bring down performance if every query in code tl;dr can use transactions every query? or should use them when performing large manipulations database? you need use transactions if want make changes or none. example if transferring money 1 person should increase one's balance , decrease another's. it's...

say have 2 constructors taking type of input. (t1 , t2 in example) i want call either of them more general constructor taking object (or superclass of t1 , t2 matter) class test{ public test(t1 input){...} public test(t2 input){...} public test(object input){ if(input instanceof t1) this((t1) input); if(input instanceof t2) this((t2) input); } the third constructor give compile error since this constructor call isn't on first line. you can use kind of factory method follows: public class test { private test(t1 input) { // ... } private test(t2 input) { // ... } public static test createtest(object input) { if (input instanceof t1) return new test((t1) input); if (input instanceof t2) return new test((t2) input); return null; } }

how calculate weights of 10 things express person's relative preference when input data follows: the list of 10 things presented in random pairs (ignoring order, vs b might shown, or b vs a, not both; , not item itself); a better b d better f h better b c better j etc. is there way rank or weight 10 items data this? , there way shorten sequence 10! / (2! (10 - 2)!) =45 questions. you're making dangerous psychological assumption here: assume "better than" relation transitive, from a > b b > c directly follows that a > c that is, without loss of generality, not case humans preferences. puts whole approach in questionable light. however, if can justify assumption, yeah, breaks down sorting problem. there's truckload of sorting algorithms out there, rely on existence of ordering relation ">". weight position in sorted list. every real-world programming language out there has library contains @ least 1 sorter algor...

i'm trying make frogger -like game patches move around , turtle can move onto safe patch. if have few patches red, how can 'move' them around if turtles? have this, seems move more 1 patch @ time , result, red patches destroyed if there more 1 red: if pcolor = red [ ask patch-at 0 1 [ set pcolor red] set pcolor black ] you ask neighbor patch (left or right) painted red , actual patch painted black or whatever default color is. for you'll want actual patch coordinates. using patch-at asks patch @ 0,1 relative whole world.

i trying build model colorize images. using lab color space. input model l channel , model trained predict , b channels. want run l channel through few convolutions , split off 2 other models independently calculate , b channels. @ end want merge them output. model = sequential() model.add(inputlayer((1, h, w))) model.add(convolution2d(64, 5, 5, border_mode = 'same', activation = 'relu')) model.add(convolution2d(64, 5, 5, border_mode = 'same', activation = 'relu')) last = convolution2d(64, 5, 5, border_mode = 'same', activation = 'relu') model.add(last) a_model = sequential() a_model.add(last) a_model.add(convolution2d(64, 5, 5, border_mode = 'same', activation = 'relu')) a_model.add(convolution2d(64, 5, 5, border_mode = 'same', activation = 'relu')) a_model.add(convolution2d(1, 3, 3, border_mode = 'same', activation = 'sigmoid')) b_model = sequential() b_model.add(last) b_model...

i've thought @persistencecontext injecting entitymanager container-managed application, while @persistenceunit injecting entitymanagerfactory. javadoc says for persistenceunit ( http://docs.oracle.com/javaee/7/api/javax/persistence/persistenceunit.html ) expresses dependency on entitymanagerfactory , associated persistence unit. and persistencecontext ( http://docs.oracle.com/javaee/7/api/javax/persistence/persistencecontext.html ) expresses dependency on container-managed entitymanager , associated persistence context. so far good, reading jpa tutorial (see https://docs.oracle.com/cd/e19798-01/821-1841/bnbqy/index.html ) contains example this the following example shows how manage transactions in application uses application-managed entity manager: @persistencecontext entitymanagerfactory emf; entitymanager em; @resource usertransaction utx; ... em = emf.createentitymanager(); try { utx.begin(); em.persist(someentity); em.merge(anotherentity);...

follow post: http://r.789695.n4.nabble.com/importing-csv-gets-me-all-16-000-columns-with-quot-na-quot-td3006480.html some background: developing program allows user upload csv files. currently, testing dataset looks like: type date lively count sm 1/13/2010 10 10 sm 1/14/2010 10 20 sm 2/15/2010 20 30 4/16/2010 5 42 1/17/2010 10 34 3/18/2010 40 54 sm 1/19/2010 10 65 sm 4/20/2010 5 67 sm 3/21/2010 40 76 sm 3/21/2010 70 76 when user imports this, fine. import method is: dataset <- read.csv(input$file$datapath) dataset <- na.omit(dataset) however, let's user saved above table in excel, saving csv. deleted last 2 columns. type date sm 1/13/2010 sm 1/14/2010 sm 2/15/2010 4/16/2010 1/17/2010 3/18/2010 sm 1/19/2010 sm 4/20/2010 sm 3/21/2010 sm 3/21/2010 if looked @ str() of table, last 2 columns wold contain na values because in excel, columns have been formatted. c...

everyone runs syntax errors. experienced programmers make typos. newcomers it's part of learning process. however, it's easy interpret error messages such as: php parse error: syntax error, unexpected '{' in index.php on line 20 the unexpected symbol isn't real culprit. line number gives rough idea start looking. always @ code context . syntax mistake hides in mentioned or in previous code lines . compare code against syntax examples manual. while not every case matches other. yet there general steps solve syntax mistakes . references summarized common pitfalls: unexpected t_string unexpected t_variable unexpected '$varname' (t_variable) unexpected t_constant_encapsed_string unexpected t_encapsed_and_whitespace unexpected $end unexpected t_function … unexpected { unexpected } unexpected ( unexpected ) unexpected [ unexpected ] unexpected t_if unexpected t_foreach unexpected t_for unexpected t_while unexpected t_do ...
